LETTERING-PEN ATTACHMENT.

Specification of Letters Patent.

Patented Sept. 13, 1921.

Application filed February 10, 1919. Serial No. 276,002.

To aZZ to 710m it may concern Be it known that I, EARLE GRAY HENRY, a citizen of the United States, residing in the city of Newberg, in the county of Yamhill and State of Oregon, have invented a new and useful Lettering-Pen Attachment, of which the following is a specification.

My invention relates to improvements in attachments for lettering pens used by draftsmen; and the objects of my improvements are to provide an attachment which will cause the ordinary lettering pen to make lines of more uniform width and to hold a larger supply of ink, and which will be easy to clean and cheap to make. 1 attain these objects by the lettering pen attachment illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view partly broken away of the attachment.

Fig. 2 is a side View of a pen fitted with the attachment.

Fig. 3 is an end view of the pen with attachment; and

Fig. iis a bottom view of the pen with attachment.

Similar letters refer to similar parts throughout the several views.

The letter A represents a pen. B is the attachment, a sheet metal stamping. Ink is placed between A and B. 0, 0 are the nibs of the pen. (Z, (Z are two round holes in A.

e, e are fingers which project up on either side oi 0, c and prevent them from spreading beyond a fixed amount, regardless of the pressure. The fingers e, e are bent up at a moderate angle so as to be easy to clean. f, f are lugs which fit into the holes (Z, (Z, and form a hinge joint between the pen A and the attachment B. They are shown rectangular'because that is the easiest shape to stamp but may be of any desired form. In

assembling, the sides of A are sprung out and over 7, f. g is the turned up rear end of B. It is long enough to press strongly against the top or" A. The downward spring of A against g, and the consequent friction, hold B in working position. Dotted lines in Fig. 2 show B swung down away from A, for cleaning. it, h are lugs for convenience in swinging B up and down.

I claim:

1. In combination with a pen having flexible nibs, of a lid having a bifurcated end, and pivotally mounted in said pen.

2. In combination with a pen having flexible nibs, of a lid having a bifurcated end, the other end of. said lid having two lugs, adapted to fit within two holes in the pen body to form a hinge.

3. In combination with a pen having flexible nibs, of a lid made in one piece, and having a bifurcated end, the other end of said lid having lugs adapted to fit within holes in the pen body, a third lug spaced between the aforementioned lugs which come into frictional engagement with the bottom of the pen to hold said lid in working position, said lid forming with the pen an ink holding cavity.

4. The combination, with a pen having flexible nibs, of a lid and a hinge, said hinge consisting of two holes in said pen and two lugs on said lid.

5. The combination, with a pen having flexible nibs, of a lid, one'end of said lid pivotally connected to said pen, and the other end of said lid having two lugs for limiting the spread of the nibs of said pen.

EARLE GRAY HENRY.
